This invention relates to improvements in fasteners for meeting-rails of window-sashes,or devices for locking the upper and lower sashes of windows together; and it has for its objects to provide a fastener which will effectually lock the sashes together, and at the same time will cause both sashes to bind tightly in their guides on the window'frame, so that rattling and shaking of the sashes in any direction will be eectually prevented.

Further objects of the invention are to provide means whereby the fastening may be employed to lock the sashes and hold them at different relative positions,whereby free ventilation of the apartment may be had wi-thout permitting any rattling of either sash inde-y pendently or together. by the present invention, which consists in the novel construction and arrangement of parts hereinafter described, illustrated in the draw-, ings, and particularly specified intheappended claims.

These objects I attain Referring to the drawings byletter, W desi ignates the lower sash of a window, and w the upper sash thereof.

To the upper horizontal `rail of sash W is secured the fastener proper, which consists of an inclosing-shell, A, of general rectangular form, which is closed on its inner face and 6o sides, but is open on its face adjoining the outer sash. At the upper portion of Shell 'A is formed the horizontal semicircularconoidal swell orenlargement B, and the inner'face of this swell is cut away, as shown, forming ahorizontal slot,b,which slot is concavo-co'nvexy in plan view, owing to the conoidal form ofthe swell B. At the opposite inner corners of shell A are formed suitable perforations, through which the retaining-screws or similar devices V7o are passed to secure the fastener in position, and from its outer corners depend studs a, for assisting in keeping the shell in position. The. top portion,O,of swell B of shell A corresponds in contour to the outer edge of slot b, looking down upon the same, and on the inner and. lower front edge of top C, at the center of thel slot b, is formed a lug, c, which forms a pivot for the actuating-.cam block F of thedevice, hereinafter described.

The outer faces of the swell B and shell A are' cut away vertically to a point near the lower edge of shell A, where the sides of the shell are slightly extended; and connected byn a horizont-al transverse bottom bar, D, as shown, in the mouth or opening d thus formed at the outer face of the shell A plays the lock. ing-plate J ,hereinafter described. f

From the top of shell A, near one inner corner thereof, depends a lug, E, which forms the pivot-bearing of thelocking-plate J, and which is provided with an extension, `e, as shown, 4, which is adapted to be turned down upon plate J after the latter is properly placed on lug E` and lprevent the plate escaping therefrom dur ing transportation ofthe fastener. Ordinarily the lug E and extension e are I nade integrahA of iron or bronze, as is the shell A; but when the shell and lug are made of friable metal the extension e should be replaced by a short wire,

which Acan; be bent down upon plate J withoutl injury to itself or other portions of the fastener. The cam-block Fconsists of a disk, G,which corresponds inA thickness to the depth of slot n.. and. 'which disk is providedenb, ass l V with" a socket, g, which corresponds' with and lis engaged by the lug c of the top part, C, of shell A, as shown. At a proper point of disk G, outside of slot b, is the handle f, by which the disk is rotated.

5 i On the undersurfaeeof diskG, and arranged in proper relation to its pivotal point, are formed the pair of depending lugs H h and the depending cam I. This cam I is formed on a partial eonvolute-curve, having its inner end I0 lying near the pivotal point of disk G to the inside of lug H, and extending thence on a eonvolute curve away from lugs H h and partly around the cireu m ference of the disk, its length being about one-third thereof. The lugs H h and cam I engage corresponding lugs and projections on the upper face of thelocking-plate J when the latter is in position and actuate the same.

The locking-plate J is iliade suiciently thin to play freely within shell A without binding against the same unduly. Its inner end is supported by the lug E, as described, and its outer end is supported and moves upon the upper Surface of bar D. The locking-plate is v of such length that when in its normal or unlocked position, in which position it lies diagonally across the shell, its outer end is flush with the outer edge of bar D; but when the plate is shifted by turning it on its pivot into locking position the outer end of the plate is extended considerably beyond the edge of bar D, so as to engage with a proper retainer secured on the outer sash.

At a point on the upper surface of plate J coinciding with the lugs and cam on the disk G are formed the projections K k, which are adapted to be engaged by the lugs H h, and the lug L, which is adapted to be engaged by the inner face of the cam I upon the disen- 40 gagement of lugs H h and projections K k. The pivot end of plateJ is rounded, as shown, to prevent any friction against the side of shell A. The outer end of plate J is provided with a head, j, as shown. This head is beveled both inwardly and downwardly or longitudinally and transversely, so that the outer edge of this head is larger than its point of j unction with the plate, as shown. This double beveled head j serves an important function in locking the sashes, as hereinafter described.

The fastener is put together and operated as4 follows: The cam block F is inserted handle rst upward through slot b, cam and lugs downward, until its socket g corresponds with the lug c. The handle f is then depressed, causing lug c to engage in socketg and pivoting cam-block F on shell A. The lockingplate J is then pressed outward partly through mouth d until its end can be engaged on lug' 6o E, where it is secured, as described, and by properly turning the cam block F the lugs, projections, and cam on the block and plate are engaged. When thus arranged, the lugs H h of cam-block F engage between them the projection k of theplate, and the lugh is similarly engaged between the lugs K k of the plate, as shown in Fig. 9.

When the lugs are engaged' andthe fastener opened, the handle f of block F stands in line with the bar D, and the cam I is entirely removed from the lug L. Then, to throw plate J into locking position, the block F is turned to the position shown in Figs. 3 and 4. 'Ihis movement of the block causes lug h to engage with projection k and turn the plateJfoi-ward rapidly until the lugs I-I h and projections K k are disengaged, owing to the different pivot-points of the plate and block, as is evident. Simultaneously with the disengagement of lugs H h and projections K 7c the cam I engages by its outer end and inner face with the lug L, and the rotary movement ofthe disk G,being continued,forces the plate J to move still farther forward until its lug L has reached the inner end of cam I. The cam I is arranged in such manner that 85 pressure thereon from lng L is transferred directly to the pivot of block F, so that the plate can be locked at any point after its lug L has engaged the cam I. The distance from lug E to lug L must be at least as greatas the shortest line drawn fromlugE to cam I at any point of rotation of the cam-block F. By reason of the convolute form of the cam great pressure 0r grip can be given to plate J to cause it to firmly hold to the retaining devices, which I will hereinafter describe.

In unlocking the fastener the cam-block F is retracted or turned, causing the lugs H h to engage projections K k and throw the plate into normal position. The projection K ispurposely made longer than projection k, to insure the engagement of lug h therewith after the locking-plate has been actuated by the cam, so that said locking-plate will be at once engaged and thrown back upon the returning of [05 the cam-block to its normal or unlocked position.

By the employment of two lugs and two projections a greater amount of quick movement can be imparted to plate J, and the operation of the device is rendered more rapid. It will be seen that, owing to the different pivotal points of the plate and block, the lugs H h will actuate the plate, as described, a greater or less degree, according as they are placed closer to or farther from their pvot, and that by setting them at varying diametrical points in relation to the end of cam I the rapidity with which the said cam is brought into action or into position for engaging lug L can be regulated. The essential features of this portion of my fastening deviceare the arrangement of lugs, projections, and cam, by which the locking-plate is first rapidly moved forward toward its locking position before engaging with the cam, and then engaged by the cam, and more slowly, but powerfully, moved into position and locked, and in which the quick-throw deylces disengage the plate simultaneously with the engagement thereby of the cam.

I will now describethe retaining devices.

M designates a serrated or toothed metal strip, the teeth m of which are angular and are formed at the side of the strip. The edges lOO IIO

IIS

of these teeth are beveled inwardly, as shown, on an angle corresponding to the bevel of head j of plate J. rI his strip M is secured to one of the vertical rails of the upper sash, w, and in a position corresponding to the fastening device on the upper rail of the lower sash. Whenit is desiredto lock the sashes together, the fastener is operated, as described, throwing the head j out and into engagement with the lower edge of one of the teeth m. Owing to the peculiar described bevels of the teeth and head j, the sashes are drawn together Vwhen pressure is exerted to close the fastener, and at the same time, owing to the lateral motion of head j in relation to the shell A, the sashes will be forced sidewise, so that if they had any lateral play before the fastener. was closed they will be bound tightly againstthe uprights of the window-frames, as well. as against each other, as clearly shown in Fig. 3.

Owing to the ,number of teeth on strip M, the sashes may be adjusted to different vpositions, so as to leave a Ventilating-space at top or bottom of window, and when the fastener is'closed, as described, the sashes are bound firmly against the Window-frames and each other in all directions, both laterally and horizontally, so that rattling thereof is prevented, which would not be the case if, as in ordinary meeting-rail fasteners, the sashes, if bound at all, are onlybound horizontally, but not laterally, and as the sashes, when worn, fit loosely between the opposite sides of the windowframes, they are liable to rattle more or less, and my invention, lby causing the sashes to bind laterally, as described, effectually prevents any such annoyance.

Instead of using the strip M, I may in some cases employ the keeper N, as shown in Figs. 2, 3, and 10, which keeper consists of a hollow rectangular shell, which has a portion of its inner wall adjoining the fastener cut away, leaving an inclined and beveled portion, a, which is adapted to be engaged by the angular head j of plate J, the action of the fastener and keeper being the same as that just described for the fastener and strip.

The keeper N is provided on its under surface with retaining-studs o, and is provided with proper eyes, O, through which pass suitable retainingscrews.

It will be observed that, owing to the peculiar arrangement of the beveled head and beveled retainer, if the rails upon which the fastener and retainer respectively rest should not be flush, the head j, when the fastener is closed, will elevate the` upper sash or depress the lower sash until the rails are flush, and-,thus when the lock is closed the sashes are forced into proper relation and present a neat appearance.

It will be observed fron. the foregoing that I have a very effeCbVe, Cheap, and usefllfast ening device, and in which the working parts are all protected, and, further, that no working part of the fastener bears upon the windowsash, but all the'bearings are contained in the fastener itself. Consequently the'fastener will not lose its effectiveness and require resetting so soon as do those fasteners in which some of the movable parts bear directly upon the wooden rail of the sash.

The fastener and keeper or strip M may be varied somewhat and ornamented in any suitable rnanner without departingffrom the essential features of my invention.
